Be itknovvn 'that LvJosHUA H MARVIL 'or V., a .citizen of the United States, residing at Laurel, in the county of Sushave invented new and useful llifnprmements in Tire-Bie- 'air-zPat'ches, fof Which the following is a specification.- 1'- v My present invention relates to patches 1c for repairing pneumatic tires, and the primary abject isj-to provide 'an improvedpatchV adapted to be inserted Abetweenthe inner tube and-.outer casing to cover a blow-out and thereby prevent blowing of the inner litube therethrough and-to protect a broken 4vor weakened portion of the outer casing and thereby prevent injury to the inner tube or blowing yof the "inner v'tube through such I brokeny or Weakened'portion. -2'0r 'lfhe patch provided-by the present invention fis capable of being applied easily :and

quickly, it will not slipor shift its position, and. it protects vthe inner tube from injury.

To tthese .and other ends, the invention nations and' arrangements of parts, all as will be hereinafter more fully. described, the

`novel features being pointed out particu- 30' larly in the. claims at the end of the speciication.

In the accompanying drawing :-l4`igure' Vvention are applicable generally to pneumatic'tlres and wheel'rims of diderenttypes and they are capable of protecting the inner tube from all Weaknesses orbreaks in the Wall' of the outer casing. rl`he patch as shown in the present instance comprises a body 1 which is preferably of segmental 5,0 form and is composed of a relatively strong or tough structure which is capable of Withstanding the relatively heavy pressure of speeication of LettersPatent.

the immer tube. A composite structure of rubber and strong fabric., such as canvas, vulcanized together, is `suit-able for this lpurpose.v The body `of the patch is preferably .curved in .a longitudinal direction in order that it imay vconform to the contour ofthe tire casing, and its transverse dimensions .are

fsuch 'that it will cover the Wall of the casing which is' ordinarily engaged b y the tube. 'A flap 2 :is provided,l as :a part of lthe patch, this iiap being composed of relatively thin earible-anaterial, for example, a sheet of canvas. This yflap is fastened at one end 'to one vof the longg'itudinal edges of-the body of the patch. by any suitable means, rivets 3 and stitching-4 being shown for this purpose. The dexible .Hap is adapted to lie within the body of the patch and is of a length vto completely encircle the inner tube transversely.` As shown, the flap is 'of -a length 'to v completely encircle the inner tube and to for-n1 part about it. The patchvis provided with means :of another convolution for holding it securely in position to prevent the patch from being forced outwardly,

particularly in those cases Where the casing is rim-cut orbro en 'adjacent to the bead,

Iand to prevent shifting of the patch Within the casing. As shown, a series of individual hooks 5 is secured to one and a series of clips 6 is secured to the opposite edge of' the patch. lThese hooks and clips are preferably' made of sheet metal having suiiicient sti'ness to retain their form.

The hooks 5 are intended to fasten upon the n bead at the respective side of the tire and the clips 6 to lie between the opposite bead and the Wheel rim.

Figs. L and 2 show a mode of applying the patch to a tire of the ordinary clencher type, Z designating the outer casing having beads 8 thereon, 9 designating the inner tubea and l0 designating the flanged rim on which the tireis mounted- In practice, the patch is introduced into the outer casing 7 at a point Where it Will cover the blow-out or broken or weakenedy portion thereof, the hooks 5 on the patch being engaged over the adjacent bead of the casing. The inner tube is placed Within the casing and the flap. 2 is Wrapped completely around the inner tube With its freeend overlapping edge of the patch,

' more or less pliable and hence of the hooks. The' or extending past the attached end thereof; `Prior to this operation, the tube maybe inflated with troduced and wrapped with the flap, the other bead of the casing `is applied to the wheel rim, the clips 6 .assuming a position between this bead and the channelofithevention is relatively thin and hence it will minimize the tendency to injure or chafethe inner tube; As the tube ,is completely encircled by the flap, the tubeis kept out of Contact with any part liable to injure it. In the construction shown, fthe flap covers the rivets or other means'of` fastening the hooks and clips to the patch and there is no possibility of the tube coming intol Contact v with these hooks or clips. By providing a series of hooks, creeping or shifting of the patch Within the casing is prevented, as any tendency of the patch-to creep will produce a rocking motion of the hooks and the hooks will then bind rmly between the bead and the flange of the rim, thereby 'resisting and preventing .such movement. vThisindividual rocking and binding action of the hooks'is permitted in the construction shown reason of the fact that the hooks are separately attached at intervals tothe body l of the patch, the body of the patch being will yield to permit the binding action sufficient air to expand it into round form. After the tube has been inpressure andr .betweenan outer and means for holding the bpdy in position v same binding nection with the clips 6. It vis preferable to use flat clips at one .-side of the patch, as shown, as this will greatly facilitate the operation of applying so in those cases where the bea casin 'have a close I claim vas my invention l.
